Answer:

y - y1 = m(x - x1)

y - -3 = 3(x - 1)

y + 3 = 3x - 3

y = 3x - 3 - 3

y = 3x - 6

Step-by-step explanation:

Thie equation is in slope-intercept form (y = mx + b)

The y-intercept is -6 .... ((0, -6) is one point on the line.

It is given that (1, -3) is also on the line. So to graph, plot those

2 points and connect them with a line.

Answer:

y = -2x+9

Step-by-step explanation:

We have a point and a slope

y = mx+b where m is the slope and b is the y intercept

y = -2x +b

Substitute the point in

3 = -2(3)+b

3 = -6+b

Add 6

3+6 = -6+6+b

9 = b

y = -2x+9

Nana can pack a bag of groceries in 6/8 of a minute, at that rate how many can she pack in 15 minutes?

rjkz [21]

So 1=6/8 minute
1=3/4 minute
multiply both sides by 4
4=3 minutes

3 times what=15
divide by 3
what=5

4=3 minutes
mulitpliy both sides by 5
20=15 minutes

answer is 20 bags

Suppose a random sample of 50 college students are asked to measure the length of their right foot in centimeters. A 95% confide

hichkok12 [17]

Answer:

A 99% confidence interval will be wider than a 95% confidence interval

Step-by-step explanation:

From the question we are told that

The 95% confidence interval for for the mean foot length for students at the college is found to be 21.709 to 25.091 cm

Generally the width of a confidence interval is dependent on the margin of error.

Generally the margin of error is mathematically represented as

$E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} }$

From the above equation we see that

$E \ \ \alpha \ \ Z_{\frac{\alpha }{2} }$

Here $Z_{\frac{\alpha }{2} }$ is the critical value of the half of the level of significance and this value increase as the confidence level increase

Now if a 99% confidence level is used , it then means that the value of

$Z_{\frac{\alpha }{2} }$ will increase, this in turn will increase the margin of error and in turn this will increase the width of the confidence interval

Hence a 99% confidence interval will be wider than a 95% confidence interval
